is there any preformance wise difference between Zotac Gtx1050 ti Mini and OC version?

Negligable difference as both are using the same GTX 1050 Ti chip. Main difference between the Mini and the OC is that the former is using stock clock speeds of 1303MHz (base) to 1417MHz (boost) while the latter is factory-OC'd at clock speeds of 1392MHz (base) to 1506MHz (boost). That is only an 89MHz difference (i.e., 0.089GHz) and would probably translate to just 2-5fps or less, depending on the game and settings.

The more noticeable difference between the two cards are its cooling and noise performance. The mini, being a single fan design, would have to spin faster/louder to dissipate heat compared to the OC, being a dual fan design, which would only have to spin slower/less noisy to produce the same amount of airflow to...

Backwards. The single fan designs spin slower on average, the much larger fan puts out a considerably higher amount of cfm. The dual fans are much smaller spin faster. The biggest advantage to the dual fans is airflow over the VRM's/vram section of the heatsink. A single fan design won't reach close to the length of the heatsink, cards being much longer than wider, so it's mostly warmed air that's traveling the fins already, which lowers the heatsinks efficiency. With the smaller fans of the dual, you get a better spread of draft down the length of the card, the triple fan designs are even better. Because of this, dual fan gpus can run higher clock speeds, more stress on VRM's and vram, with better control of temps. This is important because the VRM's/vram temps are totally unreported, there's no sensor on that part of the board, only the processor temp is accessed.

Note that the size of the PCB's of both cards are the same. The single fan mini version measures 144mm in length while the dual fan OC version measures 174mm in length. Such 30mm difference in length is only due to the fan shroud of the OC version extending past the PCB:

The mini version also lacks heatpipes (only a sunflower-heatsink is present):

The OC version provides 2 copper heatpipes and a heatsink, for better heat dissipation:

Yep. The bigger the heatsink, the better the heat piping, the higher the potential for cooling. Being OC, the processer will be running hotter than reference, but that heat has a greater area for dissipation, has a better cooling ratio, so reported temps are lower in general with equitable loads, and at max usage will still be reporting lower temps as the efficiency of the smaller cooler reaches saturation much sooner. If you manually match rpm between the cards, the dual fans will be louder, but only in that instance. Generally to get the same level or better of cooling ability, the dual fans won't need the same speeds, so end up quieter.
